Last week astronomers from around Sydney and Perth gathered at CSIRO for a workshop on “HI in Dwarf Galaxies”. A common theme were the insights, and additional questions, that came from pushing observations beyond what had been done before – deeper radio, deeper optical, wider field of view, higher angular resolution, or unbiased complete galactic neighborhoods. In the future, HI surveys like the WALLABY imaging project with ASKAP-12 and eventually those carried out with the SKA, together with an ultra-deep optical survey like that with the Huntsman Telephoto Array, will yield an unprecedented view of galactic neighborhoods and the large-scale processes that have affected the formation and evolution of dwarf galaxies.
